INDUCTION LEAK!!

The 2 rubber caps where you plug in the pipes for TB balance was worn (didn't realise it leaked air) which meant the lambda probe adjusted the motronic at idle because it thought the motor was running lean, creating the rich idling.

Cheapest fix ever on the bike!

Reset did zero. Problem still persists. Also no induction leak. What effect could the air-temperature sensor and lambda probe have on the idling? Also, I have noticed a rather rich exhaust smell when idling. Could it be dirty injectors? More bio: Catalytic converter is replaced by a y-pipe. Standard...

No induction leak. Going to try reset the Motronic this afternoon as described by http://r1150r.net/board/viewtopic.php?f=2&t=21365&p=188057&hilit=ecu&sid=cea93f4b4e39d5df527008c41de92ee9#p188057. Also.... the water down the drain thing is a myth... ------> http://www.scientificameri...

Robots are what we South Africans call traffic lights.

Bike has been run at all rpm ranges at all kinds of loads through it's whole life with me, so no chance of real carbon buildup.

Ok, so I've had my awesome rockster for 3 years now, did the usual services, TB balance etc. December I went on a long trip and when I came back, I stored the bike and disconnected the battery terminal as I would not ride for a month or so.. Got back, connected the battery and decided to do a TB bal...

I would like some help.

Did a throttle body sync (or tried). Fast idle switch doesnt increase engine rpm anymore and there's a lot of cable play on the twistgrip and fast idle (maxed out the tensioner screw). Play on the TB's are normal.

Could the problem be at the junction box then?
